Description

Technical Field

[0001] This utility model relates to the field of thickener slag discharge technology, specifically to a high-efficiency slag discharge device for thickeners. Background Technology

[0002] A thickener is a solid-liquid separation device based on gravity settling. It is usually constructed of concrete, wood, or welded metal plates as structural materials, forming a shallow cylindrical tank with a conical bottom. The cylindrical tank is also equipped with structures such as motors and rake frames. When processing slag, the slag mixed with water enters the thickener and settles. The slag settles at the bottom of the thickener and is discharged through the slag discharge port, while the upper water flows out through the overflow weir.

[0003] The existing automatic slag discharge devices for medium thickeners often experience pipe blockages during slag discharge. If these blockages are not cleared in time, they can significantly impact the slag discharge process. Therefore, this solution provides a high-efficiency slag discharge device for thickeners to address the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a high-efficiency slag discharge device for thickeners is provided. This technical solution solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency slag discharge device for a thickener includes a frame and a slag discharge hopper fixedly mounted on the frame. A hopper cover is fixedly mounted on the top of the slag discharge hopper, and a rotating cylinder is rotatably mounted on the bottom of the slag discharge hopper. A slag discharge mechanism is provided inside the slag discharge hopper. The slag discharge mechanism is composed of a slag discharge component, a cleaning component, and a loosening component. The slag discharge component includes a motor fixedly mounted on the hopper cover. The output shaft of the motor is fixedly connected to a transmission shaft. A fixed disk is rotatably mounted on the transmission shaft. A mounting block, slag discharge blades, and a connecting shaft are sequentially arranged on the lower side of the fixed disk and fixed to the transmission shaft. The cleaning component and the loosening component are both fixedly mounted on the mounting block.

[0006] Preferably, the surface of the bucket cover has an opening, and a guard is fixedly installed on the lower end of the bucket cover on one side of the opening. Inside the guard is a connecting frame that is fixedly connected to the fixed plate.

[0007] Preferably, the cleaning component includes fixed rods symmetrically fixedly connected to the front and rear sides of the mounting block. Each of the two sets of fixed rods is fixedly connected to a cleaning rod that fits against the inner wall of the slag discharge hopper. A connecting rod is fixedly connected to the lower end surface of the cleaning rod, and the upper end of the connecting rod is fixedly connected to the surface of the drive shaft. Several sets of stirring rods fixedly installed on the fixed rods are provided between the cleaning rod and the mounting block.

[0008] Preferably, the loosening component includes a mounting bracket symmetrically fixedly installed at the left and right ends of the mounting block. A sliding rod is slidably connected to the mounting bracket. A ball head block is fixedly connected to the upper end of the sliding rod, and a cutting blade is fixedly connected to the lower end of the sliding rod. The mounting bracket has a mounting groove inside, and an elastic element for resetting the sliding rod is provided inside the mounting groove.

[0009] Preferably, the elastic element includes a limiting plate fixedly installed on the slide rod, and a spring sleeved on the slide rod is fixedly connected between the lower end of the limiting plate and the inner wall of the bottom of the mounting groove.

[0010] Preferably, the lower end of the fixed disk is fixedly connected to four sets of extrusion blocks for driving the ball head block to move downward, and the four sets of extrusion blocks are uniformly arranged in a ring on the fixed disk.

[0011] Preferably, both ends of the connecting shaft are fixedly connected to the inner wall of the rotating cylinder, and guide blades are fixedly connected to the inner wall of the rotating cylinder.

[0012] Compared with the prior art, this utility model proposes a high-efficiency slag discharge device for thickeners, which has the following beneficial effects: This utility model includes a slag discharge mechanism, which consists of a slag discharge component, a cleaning component, and a loosening component assembly. The slag discharge component is driven by a motor, which drives the transmission shaft to rotate, thereby causing the mounting block, slag discharge blades, and connecting shaft to rotate synchronously. The installation block drives the front and rear cleaning components to rotate synchronously. The cleaning rod in the cleaning component scrapes off the slag adhering to the inner wall of the slag discharge hopper to prevent clumping and sticking to the wall. The stirring rod stirs the slag in the hopper to prevent the slag from being compacted and to ensure that the slag is loose and easy to transport. The drive shaft drives the loose part to rotate. Each rotation of the ball head block at the top of the slide rod pushes the slide rod down and compresses the spring multiple times under the drive of multiple sets of extrusion blocks at the bottom of the fixed plate, so that the cutting blade cuts the clumps. After leaving the extrusion blocks, the cutting blade moves up under the reset of the spring, so that the cutting blade continuously cuts up and down during the rotation around the drive shaft, continuously breaking up the clumps of slag and preventing blockage. Finally, the rotation of the slag discharge blades continuously pushes the sludge deposited at the bottom of the slag discharge hopper downwards, allowing it to enter the rotating drum. The fixed connection of the connecting shaft causes the rotating drum to rotate with the drive shaft, enabling the internal guide blades to effectively cooperate with the slag discharge blades, guiding the slag conveyed to the bottom towards the outlet and preventing slag accumulation. This effectively solves the problems of clogging, wall adhesion, and agglomeration that easily occur in thickener slag during the slag discharge process, effectively improving the overall slag discharge efficiency and stability, and reducing overall costs.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Reference Figure 1 and Figure 3 As shown, a high-efficiency slag discharge device for a thickener includes a frame 1 and a slag discharge hopper 2 fixedly installed on the frame 1. A hopper cover 3 is fixedly installed on the top of the slag discharge hopper 2, and a rotating cylinder 4 is rotatably installed on the bottom of the slag discharge hopper 2. A slag discharge mechanism 5 is provided inside the slag discharge hopper 2. The slag discharge mechanism 5 is composed of a slag discharge component 51, a cleaning component 52, and a loosening component 53. The slag discharge component 51 includes a motor 511 fixedly installed on the hopper cover 3. The output shaft of the motor 511 is fixedly connected to a transmission shaft 512. A fixed disk 513 is rotatably installed on the transmission shaft 512. A mounting block 514, a slag discharge blade 516, and a connecting shaft 517 are sequentially arranged on the lower side of the fixed disk 513 and fixed on the transmission shaft 512. The cleaning component 52 and the loosening component 53 are both fixedly installed on the mounting block 514.

[0017] Furthermore, this device is equipped with a slag discharge mechanism 5, which consists of a slag discharge component 51, a cleaning component 52, and a loosening component 53. The slag discharge component 51 is equipped with a motor 511 for driving. The motor 511 drives the transmission shaft 512 to rotate, which can drive the mounting block 514, the slag discharge blade 516, and the connecting shaft 517 to rotate synchronously. The mounting block 514 can then drive the cleaning component 52 and the loosening component 53 mounted on its surface to rotate, so that they can cooperate with the slag discharge component 51 to achieve a high-efficiency slag discharge effect. This effectively solves the problems of blockage, wall adhesion, and agglomeration that easily occur in the slag discharge process of thickened slag, effectively improves the overall slag discharge efficiency and stability, and reduces the overall cost.

[0018] Reference Figure 3 As shown, specifically in this embodiment, the surface of the bucket cover 3 has an opening 301, and a barrier 302 is fixedly installed on the lower end of the bucket cover 3 on one side of the opening 301. A connecting frame 303 fixedly connected to the fixing plate 513 is fixedly connected inside the barrier 302.

[0019] Furthermore: the opening 301 facilitates material feeding, and the enclosure 302 effectively protects the internal connection, preventing it from coming into contact with slag.

[0020] Reference Figure 4 As shown, specifically in this embodiment, the cleaning component 52 includes fixed rods 521 symmetrically fixedly connected to the front and rear sides of the mounting block 514. Each of the two sets of fixed rods 521 is fixedly connected to a cleaning rod 522 that fits against the inner wall of the slag discharge hopper 2. A connecting rod 523 is fixedly connected to the lower end surface of the cleaning rod 522. The upper end of the connecting rod 523 is fixedly connected to the surface of the drive shaft 512. Several sets of stirring rods 524 fixedly installed on the fixed rods 521 are provided between the cleaning rod 522 and the mounting block 514.

[0021] Furthermore: the fixing rod 521 is symmetrically fixed on the front and rear sides of the mounting block 514 and rotates with the mounting block 514. It serves as the support arm for the cleaning rod 522, fixing the cleaning rod 522 to the mounting block 514 and transmitting rotational power. The outer end of the cleaning rod 522 is tightly fitted to the inner wall of the slag discharge hopper 2. When it rotates with the fixing rod 521, it can scrape off the slag adhering to the inner wall of the slag discharge hopper 2, preventing the slag from sticking to the wall and caking, avoiding affecting the slag discharge channel, and effectively reducing subsequent cleaning and maintenance costs. One end of the connecting rod 523 is fixed to the lower end of the cleaning rod 522, and the other end is fixed to the surface of the drive shaft 512, which effectively enhances the fixing stability of the cleaning rod 522 and prevents the cleaning rod 522 from deforming or shifting due to the scraping resistance. The stirring rod 524 is fixed on the fixed rod 521 and rotates with the fixed rod 521 to stir the slag in the slag discharge hopper 2, prevent the slag from accumulating and compacting, keep the slag in a loose state, and facilitate the conveying of the slag by the slag discharge blades.

[0022] Reference Figures 5-6 As shown, specifically in this embodiment, the loosening member 53 includes a mounting bracket 531 symmetrically fixedly installed at the left and right ends of the mounting block 514. A sliding rod 533 is slidably connected to the mounting bracket 531. A ball head block 536 is fixedly connected to the upper end of the sliding rod 533, and a cutting blade 537 is fixedly connected to the lower end of the sliding rod 533. A mounting groove 532 is provided inside the mounting bracket 531, and an elastic element for resetting the sliding rod 533 is provided inside the mounting groove 532.

[0023] Reference Figures 5-6 As shown, specifically in this embodiment, the elastic element includes a limiting plate 534 fixedly installed on the slide rod 533, and a spring 535 sleeved on the slide rod 533 is fixedly connected between the lower end of the limiting plate 534 and the bottom inner wall of the mounting groove 532.

[0024] Reference Figure 5 As shown, specifically in this embodiment, the lower end of the fixed disk 513 is fixedly connected to four sets of pressing blocks 515 for driving the ball head block 536 to move downward. The four sets of pressing blocks 515 are uniformly arranged in a ring on the fixed disk 513.

[0025] Furthermore, an installation frame 531 is provided, which is symmetrically fixed at both ends of the installation block 514 to provide sliding guidance for the slide rod 533 and restrict the slide rod 533 to move only in the up and down direction. The upper end of the slide rod 533 is connected to the ball head block 536, and the lower end is connected to the cutting blade 537. When the ball head block 536 at the top rotates with the installation frame 531 and the drive shaft 512, the extrusion blocks 515 evenly arranged on the fixed plate 513 sequentially extrude the ball head blocks 536 on both sides, causing them to slide up and down along the installation frame 531, triggering the reciprocating motion of the cutting blade 537. This allows the cutting blade 537 to continuously cut and crush large pieces of slag during rotation and periodic downward movement, preventing clumps of slag from blocking the slag discharge channel and improving the smoothness of slag discharge. The elastic element allows the compressed spring to recover its deformation after the ball head block 536 leaves the extrusion block 515, pushing the limit plate 534 upward and causing the slide rod 533, ball head block 536, and cutting blade 537 to reset, preparing for the next cut.

[0026] Reference Figure 3 and Figure 5 As shown, specifically in this embodiment, both ends of the connecting shaft 517 are fixedly connected to the inner wall of the rotating cylinder 4, and a guide blade 401 is fixedly connected to the inner wall of the rotating cylinder 4.

[0027] Furthermore, the rotation of the slag discharge blades 516 can continuously push the sludge deposited at the bottom of the slag discharge hopper 2 downwards, allowing it to enter the rotating cylinder 4. The fixed connection of the connecting shaft 517 causes the rotating cylinder 4 to rotate with the transmission shaft 512, so that the guide blades 401 inside can effectively cooperate with the slag discharge blades 516 to guide the slag material conveyed to the bottom to the outlet, avoiding slag accumulation.

[0028] The working principle of this utility model is as follows: During use, material is easily fed in through the opening 301. After feeding, the motor 511 in the slag discharge mechanism 5 is started, and the motor 511 drives the transmission shaft 512 to rotate, which can drive the mounting block 514, the slag discharge blade 516 and the connecting shaft 517 to rotate synchronously. The mounting block 514 can then drive the cleaning part 52 and the loosening part 53 mounted on its surface to rotate. Among them, the fixing rod 521 in the cleaning component 52 is symmetrically fixed on the front and rear sides of the mounting block 514. It rotates with the mounting block 514 and serves as the support arm for the cleaning rod 522. It fixes the cleaning rod 522 to the mounting block 514 and transmits rotational power. The outer end of the cleaning rod 522 is in close contact with the inner wall of the slag discharge hopper 2. When it rotates with the fixing rod 521, it can scrape off the slag adhering to the inner wall of the slag discharge hopper 2, preventing the slag from sticking to the wall and caking, avoiding affecting the slag discharge channel, and effectively reducing subsequent cleaning and maintenance costs. One end of the connecting rod 523 is fixed to the lower end of the cleaning rod 522, and the other end is fixed to the surface of the drive shaft 512. It effectively enhances the fixing stability of the cleaning rod 522 and prevents the cleaning rod 522 from deforming or shifting due to the wall scraping resistance. The stirring rod 524 is fixed on the fixing rod 521. It rotates with the fixing rod 521 and can stir the slag in the slag discharge hopper 2 to prevent the slag from accumulating and compacting, keeping the slag in a loose state, which is convenient for the slag discharge blades to transport. When the ball head block 536 at the top of the loosening part 53 rotates with the mounting frame 531 and the drive shaft 512, it is squeezed by the evenly arranged extrusion blocks 515 on the fixed plate 513, causing the ball head blocks 536 on both sides to slide up and down along the mounting frame 531, triggering the reciprocating motion of the cutting blade 537. This allows the cutting blade 537 to continuously cut and break up large pieces of slag during rotation and periodic downward movement, preventing lumpy slag from blocking the slag discharge channel and improving the smoothness of slag discharge. The elastic element ensures that when the ball head block 536 leaves the extrusion block 515, the compressed spring recovers its deformation, pushing the limit plate 534 upward, which in turn resets the slide rod 533, the ball head block 536, and the cutting blade 537, preparing for the next cut. Finally, the rotation of the slag discharge blade 516 can continuously push the sludge deposited at the bottom of the slag discharge hopper 2 downwards, allowing it to enter the rotating cylinder 4. The fixed connection of the connecting shaft 517 causes the rotating cylinder 4 to rotate with the transmission shaft 512, so that the guide blade 401 inside can effectively cooperate with the slag discharge blade 516 to guide the slag material conveyed to the bottom to the outlet, avoiding slag accumulation.
